That also would be more in-line with the way reasonably priced CAD software works. Do you use B4. Am I missing something? All are perfectly fit.

Am I missing something?
Such issues are the result of project complexity, size, uniqueness and regulation, as well as the need for virtual team collaboration. The Eng-Tips staff will check this out and aame appropriate action.
You just have to document it somewhere that your model is at MMC. I was just trying to make point, that modeling to nominal is nothing to look down at.
Do you use B4. Our drawings reference ISO Click Here to join Eng-Tips and talk with other members! This is probably the company's decision.
Promoting, selling, recruiting, coursework and thesis posting is forbidden. Quote pmarc At least nowhere as,e the standards it is said that they shall be done in the nominals. We don't really use the ISO or B4.

LIMITS, FITS, ALLOWANCES AND TOLERANCES
Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Are you saying that your as,e is placing 10 mm bolts into 10 mm holes? For companies based in North America, it seems that the limits and fits system is almost never used. The Architecture, Engineering and Construction AEC industry is constantly looking for process improvements to better manage potential project delays and costs.
Do you use B a lot? - Drafting Standards, GD&T & Tolerance Analysis - Eng-Tips
Probably there are firms that follow other fancy rules - at least I wouldn't be surprised about that. Occasionally but not systematically.
Close this window and log in. To CheckerHater, for bolt applications, we don't tolerance this way.
The automotive company I used to work never uses B4. It's easy to join and it's free. All are perfectly fit. Students Click Here Join Us! If you decide to change your fits, say, from H6 to G6 you don't have to re-model every hole in your model. Now our drawings are full of H6, f9, type of callouts whenever there is hole and shaft, or groove and tab fit.
That's not to say I like or dislike the B4. In "standards" it says better then that. That also would be more in-line with the way reasonably priced CAD software works.
